Abstract

|
|
|
Concentration of hormones and blood components at the last fatting stage was changed before slaughter in Hanwoo steers and bulls. Two months before slaughter and shipment, concentration of cortisol and creatinine was increased, but that of calcium was decreased. Concentration of insulin growth factor-1 (IGF-1) was decreased after shipment, and inorganic phosphorus (IP) was decreased at slaughter. It is unclear that changes of concentration in between 2 months before slaughter and shipment were either caused by aging or stresses (abstinence, environmental change, blood drawing, and shipment). Changes of blood concentration between shipment and slaughter may be accounted for overall responses from abstinence, shipment, and unfamiliar environment. A positive correlation between 2 months before slaughter and before shipment was detected for IGF-1, total protein (TP), albumin, creatinine, high density lipoprotein cholesterol (HDLC), and globulin in steers, and creatinine and globulin in bulls. A positive correlation between 2 month before slaughter and slaughter was detected for IGF-1, blood urea nitrogen (BUN), IP and HDLC in steers, and creatinine in bulls. A positive correlation between before shipment and slaughter was detected for testosterone, IGF-1, creatinine, triglyceride, HDLC and globulin in steers, and TP, creatinine, HDLC and globulin in bulls.
